APPARATUS FOR ROLLING RINGS, 80G.

SPECIFICATION forming part of Letters Patent No. 554,482, dated February 1 1, 1896.

Application filed May 21, 1895. Serial No. 550,066. (No model.)

To all whom it may concern:

Be it known that we, WVILLIAM D. Enron and JAMES EYNON, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Rolling Rings, &c., which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of a novel construction of apparatus for rolling rings, &c. means being provided for causing the material which is rolled to assume a circular shape, and pro vision being also made for stripping the same from the rolls automatically without necessitating any additional attention on the part of the operator.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure lrepresents a side elevation, partly in section, of an apparatus for rolling rings, to. embodying our invention, with the guide removed for clearness of illustration. Fig. 2 represents a plan View of the same. Fig. 3 represents a section on line 00 00, Fig. 1, viewed in the direction of the arrows. Fig. 4 represents a section on line y 1], Fig. 1, viewed in the direction of the arrows. Fig. 5 represents a side elevation similar to Fig. 1, showing the relative position of the rolls and the guide for bending the metal into rings. Fig. 6 represents a section on line 00 m, Fig. 1, showing a piece of metal in the act of being bent.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the main shaft, which is supported in suitable bearings in the standards B, O, D, and E, and has mounted thereon the pulley F, to which power may be applied.

G designates aroll mounted upon said shaft A intermediate the bearings O and D, said roll G having the arc J H K of reduced diameter, while the arc J L K is of greater diameter, said latter arc being provided with a groove M.

N designates a gear which is mounted upon said shaft A, and is adapted to mesh with the pinion P, which is mounted upon the shaft S, between the bearings Q and B, said pinion and shaft A having a feather and groove T common thereto, whereby the shaft S rotates in unison with said pinion, but is capable of longitudinal movement relative thereto without'causing any annular movement of the pinion, any sidewise movement of the latter being prevented, since the same is held between the bearings Q and R, the holes through thesame being of sufficient diameter to allow the rotation therein of said feather, as is evident.

U and V designate collars, which are attached to said shaft S, between the bearings Q and E, said collars being adapted to hold in position the lower bifurcated portion X of the yoke WV, the prongs of said portion X straddling the shaft S, as will be understood from Fig. 3, while the upper portion of said yoke may be provided with a suitable roller Y, which is adapted to engage the walls of a cam-groove B in the roll A, said yoke NV being supported inposition by means of the strap Z, which encircles said shaft A, as will be apparent. The lower portion of the bearing D is provided with an extension 0, which projects from a side thereof, within which rotates the bearing or cylinder E, the latter having attached thereto the grooved roller G, which is adapted to rotate at intervals in vertical alignment with said roller G, the face D of said bearing 0 serving as a stripper to strip thematerial rolled from the small roll G, as will be hereinafter explained, the said G having a journal H which extends a short distance into the bearing in the lower portion of the standard 0.

A designates a guide employed to cause the metal blanks or rods employed to ben d into the desired shape, the same consisting of the body portion B which has an arm 0 by which it is attached to an adjacent standard, said body portion having the curved plain face D which is adjacent the small roll G, the edges of the curved face D terminating adjacent the two' large rolls, so that the metal rod or blank E will be compelled to assume the desired bend, as indicated in Fig. 6, the relative position of said rolls and guide being best seen in Figs. 5 and 6, said guide, however, being omitted from the other figures for the sake of clearness of illustration.

The operation is as follows: Power having been applied to the pulleyli, and the shaftA thus caused to rotate in the direction indi cated, it will be seen that this rotation will be imparted by means of the gear N to the pinion P, thereby causing the shaft S and the roll G to rotate. In the meantime, however, the engagement of the roller Y of the yoke IV with the cam-groove B will cause the said shaft S to move alternately from the left to the right, and vice versa, by reason of the contour of said cam'groove B, as seen especially in Fig. 2, it being remembered that said shaft S can move freely through the pinion P in either direction, but is caused to rotate in unison therewith by means of the feather and groove T, thereby moving the groove in the roller G in the present instance to the left of the groove M at certain intervals, as is evident.

If now a rod, bar or other piece of metal K of the required length is interposed between the rolls L and G at about the time that the point J is about to contact with said roll G, it will be seen that said metal K will be caused to assume the outline of a ring by reason of the contact of its extremity with the curved face D of the guide, as will be understood from Fig. 6, and as soon as the said roll G has revolved, so that the reduced portion 11 is ad jacent the roll G, the ring will be tightly in engagement with said roll G, and at substantially this instant, by reason of the engagement of the yoke WV with the cam in the-manner described, the roll G is caused to move to the left, whereupon the edges D of the bearing 0 will act as a stripper and will push the completed ring off of said roll G, the latter being thus given a longitudinal or endwise movement without necessitating the stopping of its rotation, as is evident.

In the preferred embodiment of our invention a roll A having a raised groove portion B and a recessed portion G is placed under and in alignment with the roll G, the latter and the said roll A being substantially the same in all respects, and their positions relative to each other being indicated in Fig. 4:, said roll A being mounted 011 the shaft D which rotates in suitable bearings E and has attached thereto the gear F which meshes with the pinion P, so as to revolve in unison therewith, the function of said roll A being to assist in supporting and shaping the material which is being rolled.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
